This invention relates to improvements in dyeing machinery and more particularly in some of its features to improvements in drive mechanism for dyeing machines of the rotary reel type.

It is a general object of the inventionto improve and perfect dyeing machines of the class mentioned and drive mechanism therefor, so as to provide a simple, efficient and sturdy construction which is economical from standpoints of production and operation. i

A further object is the provision, for ma- :hines of the classmentioned, of an improved unitary self-contained power transmission mechanism which is easily placed in position or removed, and the parts whereof are readily accessible for inspection, repair, adjustment, etc. i

A further object is the provision of an improved drive mechanism for machines of the class mentioned and having an improved manual drive associatedtherewith for ad justment of the machine through a comparatively limitedrange when the power drive is ii'ioperative. j

A further object isthe provision of an improved unitary power transmitting gear box for laundry machines or the like.

Qther objects will be :in part pointed out in connection with the following detailed. description of an illustrative but preferred embodiment of the invention and will bein part obvious in connection therewith.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts,'whieh will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated inthe claims.

For a complete Understanding of the natur: and objects of the invention reference is had to the following detailed description, and to the accompanying drawings illustrating a preferred embodiment, and in which:

. Referring to the drawing for a detailed description of the embodiment OftllGinVGl1- tion there shown, the dyeing machine includes a dyetank 10 and an inner rotatable receivingdrum orreel 11 which is arranged for reception of'thegoods under treatment. The tank is preferablyprovided with sup porting end frames 12 and 13 having fiat inner faces and flanged outer faces, down wardly extending pedestals 14 being prefer '70 ably integrally secured to the framesw Each frame has a marginal frame member including a bottom member 15, sidemenibers 16 and top member: 17 forming a substantially continuous perimetrical frame part1 :fInt'ermediate the side frame members are spaced upright frame members 18 and a horizontal member 19 extending between the spaced upright member-sand integrally connected therewith. 19 affords a brace between the upright members and may be continued to connect with one ormoreof the upright side ;members; it also provides a support forparts of the driving mechanism. 7 preferably I ust as an integral unit and are provided with horizontalrigidifying flanges which maybe continued around'tho pedestal 14 as shown; The end frames have flat smooth inner faces fortlie purpose of providing a seat for supporting end platesQO, and; they are supported in spaced relation by-means of tie rods 21. Thebottonr plate 22 is flanged outwardlymarginally as indicated at-23 and connected by, welding or by 9 bolts 24, or both, to outwardly protruding edges of the end plates 20 so as to provide liquid proof joints; Thebottom plate is preferably continued upwardly to form the sides of the tank. The top of the tank is 9 closed by the cover 25 hinged to a longitudinel rod 26 carried by brackets 27 on the end frames. It will be noted that the inner smooth surfaces ofthe end frames provide a firm back support or seat for the end plates for attachment of the driving'parts t0 the The horizontal frame member 80 All the frame membersare 85 end frame; these blocks may be formed integrally with the respective frame members,

or made as separate parts.

The reel is mounted for rotation within,

the tank, being supported at one end by means of a trunnion seated within an open top bearing 29 supported by the end frame 7 13, and at the opposite end by means of a supporting trunnion shaft 30' which is removably but non-rotatably seated in the end or trunnion plate of the reel. The shaft 30 not only provides the driving connection for the reel but supports it upon the gear box as more fully pointed out below. An inlet pipe 31 is provided for the introduction of dye liquid and admin outlet is provided at 32. Heating fluidysuch as steam, may be introduced-through:anozzle 33 shown as disposed near the bottom of the tank.

I For driving the reel in carrying outthe dyeing process, power transmission connections are provided including ,a gear train housed within agear casing 34 and forming a unltary drive mechanism or gear box for transmitting power from a driving motor to the rotary reel. This casing is provided'with lugs 36for attachment to the end frame, being arranged for seating against the blocks 28 as shown; The gear casing is provided with a removable cover so the interior space may contain lubricant for the interior operating parts. Mounted upon studs carried by the rear wall of the gear casing are spur gearsZ-Bfil 39; and a toothed sector 40 connected to a pin on the gear 39 by means of a pitman 41. The toothed sector meshes with a pinion 42 which is prefer ably integral with the driving shaft 30. the latter being carried in bearing supports in the casing walls. A worm wheel l3 also supported by one of said studs and secured to the gear 38 for rotation therewith, meshes with a worm'ell carriedbya shaft 45 mounted in oil-tight bearings in the ,casing'walls as particularly shown in 3.

As shown in Fig. 3 the worms'haft 45 ex tends from the casing at one end to which is attached a'hand operating wheel 46, and at the other end for connection to a driving gear 47 preferably mounted ina leasing 48 carried by the end frame 12 through the at taching blockQS audarranged to be t riven bv apinion 49 on the motor shaft. It will til LII

be observed 1) that the motor 35 is mounted on a lowerintegral enlargement of the upright frame member 18 and is wire-cl for control by a snap switch mounted on the upper part of the end frame.

Referring more particularly to Figs. 2 and 6, itwill beseen that the gear casing is provided with a projection 5Q forming a casing or sleeve for the driving shaft 30. This sleeve is arranged to abut at its outer end with the end plate 20 of, the tank and a flanged threaded collar 51 surrounding the liquor from the tank.

shaft is arranged to be set up tightly to press the end plate firmly against the end of the sleeve so as to make a tight oint. Packing washers may be introducedif desired forv insuring tight connections at this point. This sleeve'ls also provided with interiorv packing 52 surrounding the shaft and held resiliently but firmly in place by a spring 53. housed within the sleeve. The purpose of the packing 52' is toprovide an oil proof joint for preventing seepage of the oil at this point and to prevent escape of the It will be noted that the drive shaft 30 traverses the end plate 20 and the sleeve abuts the same at a .point' spaced from the frame members whereby the end plate isyieldable inwardly or outwardly to compensate for slight displacements of the gear boX so'precise positioning thereof is unnecessary. It will also be noticed that the shaft 30 is removable when 'the casing cover 37 is removed thus facilitating removal of the reel and furthermore that the reel is supported directly upon the gear casing through this shaft. As clearly shown in Fig. .6, the shaft 30 may extend into bearing relation with the cover plate 87 which for this'puroose is provided with a supporting bearing, and this contact of the shaft with the cover together with the contact provided by the sidefaces-of the driving pinion 42. limits longitudinal displace- .ment of the shaft 30.

From the foregoing it will be clear that the reel is given a reciprocatory rotary motion through the gear train described when the motor is set in operation. ,Due to the irreversible driving gear train provided by the wormo lfand cooperating.worm wheel e8 as describedyit would. bedi'liicult or impossible to turn the reel by. direct application of turning force or moment thereto to bring it into proper position for reception or removal of'goods. However the hand wheel elti connected directly to the worm shaft offers a convenient means for accomplishment of this adjustment through relatively small angles when the motor is inactive. This irreversible driving mechanism prevents accidental turning of the drum as for example during loading or unloading when there may be considerable unbalane of the gear train is not interrupted by removal of the gear casing cover 37 thus permitting inspection of the parts when in operation.

Since certain changes may be made in the above construction and different embodiments of the invention could be made with out departing from the scope thereof,it is intended that all matter contained in the above description or shown in the accompanying drawing shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specific: features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
